This paper presents a set of equations describing certain fracture mechanics parameters for chevron-notch bar and rod specimens. They are developed by fitting earlier compliance calibration data. Numerical differentiation must be used to determine the minimum stress intensity factor and the critical crack length, and the problem this presents for these specimens is discussed.
